• ALWAYS wear safety glasses.

• ALWAYS wear ear protection.

• Only use fasteners of the type specified in the manual.

• Do not use any stands for mounting the tool to a support.

• NEVER use the tool for any other purpose than specified in this manual.

• NEVER use this tool on scaffolds, stairs, ladders or similar workplaces.

• Don’t use the tool to close cases or crates.

• Don’t use the tool for attaching transportation safety devices, e.g., on vehicles and carriages.

• Before use check proper function of contact trip. Never use this tool when either trigger switch or contact trip is damaged.

• Use quick-action couplings for connection to the compressed air system. The non-sealable nipple must be fitted to the tool in such a way that no compressed air remains in the tool after disconnection.ENGLISH

• ALWAYS use clean, dry compressed air. Do not use oxygen or combustible gases as an energy source for this tool.

• The maximum allowable air pressure of the tool shall NEVER be exceeded.

• Only connect this tool to an air supply where the maximum allowable pressure of the tool cannot be exceeded by more than 10%. In case of higher pressures, a pressure reducing valve including a downstream safety valve shall be built into the compressed air supply.

• Only use hoses with a rating exceeding the maximum operating pressure of the tool.

• To prevent an unnecessarily high noise level, increased wear and resulting failures, the nailer should be operated with the lowest pressure required for the work process.

• DO NOT use oxygen, combustible gases or any other reactive gases for operating compressed air. Danger of explosion and/or serious personal injury may result.

• Before transporting the tool, disconnect it from the compressed air system, especially where ladders are used or where unusual physical posture is adopted while moving.

• Disconnect the tool from the air supply when it is not in use.

• Avoid weakening or damaging the tool, for example by: – punching or engraving – modifications not authorised by the manufacturer – guiding against templates made of hard material such as steel – dropping or pushing across the floor – applying excessive force of any kind

• Do not use the equipment as a hammer. WARNING! Keep the nailer, loaded or unloaded, pointed away from yourself and others. Serious personal injury may result.

• While working, hold the tool in such a way that no injuries can be caused to the head or to the body in the event of a possible recoil due to a disruption in the energy supply or hard areas within the workpiece.

• NEVER actuate the fastener driving tool into free space.

• In the work area, carry the tool at the workplace using only one handle, and NEVER with the trigger actuated.

• Consider the conditions in the work area. Fasteners can penetrate thin workpieces or slip off corners and edges of the workpiece, and thus put people at risk. The length of the nails used should be no longer than the thickness of the workpieces. If the nails are longer than the workpiece thickness this could cause a rebound of the nails if the workpiece is placed on a hard surface, e.g., concrete, steel.

• Do not drive fasteners close to the edge of the workpiece. ALWAYS keep a distance of at least 25 mm from the edge of the workpiece so nails will not destroy the workpiece.

• Do not drive fasteners on top of other fasteners.

• Only use spare parts specified by the manufacturer or his authorised agents.

• Have repairs carried out only by the manufacturer or authorised agents having due regard to the information given in the manual and using the appropriate tools and equipment.

• Replacement of contact trip spring is recommended every 3-4 years to ensure personal safety.

• Do not disassemble or block any parts of the fastener driving tool such as the safety yoke.

• Have the tool serviced properly and at regular intervals.

• ALWAYS wear safety gloves to reduce the risk of personal injuries. Residual Risks

• The following risks are inherent to the use of these machines: – Injuries caused by improper handling of the tool. – Loss of control due to not gripping tool firmly. – Muscle strain of arms and hands, especially when working overhead. Always take regular breaks when working for long periods of time. – Do not use the tool while you are tired or under influence of drugs, alcohol or medication. A moment of inattention while operating may result in serious personal injury.

• In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are: – Impairment of hearing. Under someENGLISH

conditions and duration of use, noise from this product may contribute to hearing loss. – Loss of control caused by recoil. – Risk of injury caused by pinch points, sharp edges and improper handling of workpiece. – Risk of injury caused by sharp edges when changing nails or inserting nail sticks. – Discomfort to hand and arms.

WARNING: To reduce the risk of

serious personal injury, ALWAYS wear proper eye and hearing protection when operating this tool. The tool can be actuated using one of two modes: single sequential action trigger mode and bumpENGLISH

action trigger mode. The trigger installed on the tool as described in the Trigger section of this manual determines the mode of operation. SEQUENTIAL ACTION TRIGGER - (GRAY) The sequential action trigger’s intended use is for intermittent nailing where very careful and accurate placement is desired. To operate the nailer in sequential action mode:

1. Depress the contact trip firmly against the work

2. Depress the trigger.

CAUTION: A nail will fire each time the trigger is depressed as long as the contact trip remains depressed. BUMP ACTION TRIGGER - (BLACK) The bump action trigger’s intended use is for rapid nailing on flat, stationary surfaces. Using the bump action trigger, two methods are available: place actuation and bump actuation. To operate the tool using the place actuation method:

1. Depress the contact trip against the work

2. Depress the trigger.

To operate the tool using the bump actuation method:

1. Depress the trigger.

2. Push the contact trip against the work surface.

As long as the trigger is depressed, the tool will fire a nail every time the contact trip is depressed. This allows the user to drive multiple nails in sequence. CAUTION: Do not keep trigger depressed when tool is not in use. Keep the lock-off switch rotated to the right (OFF) when the tool is not in use. Loading the Tool (fi g. 1)

WARNING: Keep tool pointed in a safe

direction when loading nails.
